The Bertillon system, also known as anthropometry, was a method of identifying criminals through precise measurements of various body parts. However, over time, other synonyms have come into use for this term. One of the most common is "measurement system," which accurately describes the process. Another synonym is "criminal identification system," which focuses more on the application of the system in law enforcement. The term "biometric system" also applies, given that anthropometry relies on unique physical characteristics to identify individuals. Lastly, "physical identification system" highlights that identifying criminals through their physical attributes is the main aim of the Bertillon system.
